Calcium Deficiency?

This month old plant was healthy up until this week when I both topped it and started feeding nutes. Growing outdoors in a mix of Ocean Forest, Happy Frog, and perlite. What do you guys think?

That does not seem like a purely Calcium issue. It's a micronutrient issue, which to me, means to check ph first.

That is a really big pot for that little plant. It did not need nutes for a long time. Topping it didn't cause it. How often do you water? How much water do you use when watering?

Thanks. My ph seems to be fine it's at 6.4. Keeping my fingers crossed as whatever it is has slowed down spreading to the other leaves the last couple days.

Thanks. The plant was 5 nodes high before I topped it and a month old. Cotyledon leaves were yellowed out so I decided to feed it at 1/2 strength (in hindsight I should have maybe started at 1/4). The last time I watered prior to feeding it was a week ago. I did just flush it again in case it was a nute burn issue. I'm going to wait for it to dry out again before I give it just ph'd water.

Is that the soil ph or the water you put into the soil? If your soil ph is off you will need to treat the soil or use chelated nutrients until it can fix itself

That's my soil slurry ph. I'm running NFTG.
